My mp20 is flashing red and green, I opened it and the bearings are good. Before this thing happened, I have water spilled on top of the controller box. I really think my controller has some parts shot.
If u have a spare mp20 or mp40 controller , may I connect to my dry side motor to try it out? Really appreciate any help. The controller box has to be opened to connect the dry side motor. I have opened mine many times , never had any problem.
